The meeting points of two rays is called a vertex
The original figure is called the pre-image. After the transformation it becomes the image.
This is called the Orientation.

If the start and end points of a figure are same, then it is called a closed figure. Examples can be a square or a triangle or a pentagon.
A solid with smooth faces, sharp edges, and points is called a polyhedron. It is a three-dimensional figure composed of polygons. Some common examples include cubes, pyramids, and prisms.
Its called points maybe
Scale factor
Noncollinear points are points which are not all on a common line.
Triangle: A figure formed by exactly three (non-colinear) points joined by line segments is a triangle. A figure formed by three or more points is generally called a polygon. Of course, if all of the points are co-linear then there is not much of a figure. A polygon has 3 or more sides.
They are called equidistant points and form points on a sphere for a solid or a circle on a plane figure.
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
